10. put the objects in #6 - 9 (potato, iphone, roller coaster, and water balloon) in order from least to greatest potential energy
Answer
Explanation:
Step1: Recall potential - energy formula
Potential energy (PE = mgh) (assuming gravitational potential energy near the Earth's surface). For the same height (h) and gravitational acceleration (g), potential energy is proportional to mass (m).
Step2: Compare masses
A water - balloon is usually the lightest among the given objects, followed by an iPhone, then a potato, and a roller - coaster is the heaviest.
Answer:
Water balloon, iPhone, potato, roller coaster
